Lian Li PC-X900 Case/Chassis

I ran into a number of issues when building this machine, the biggest one was an electrical short caused by the stock screws and power supply mount. This was remedied by removing the removable power supply bracket that came with the case, this bracket was used to make the power supply mounting tool less.

The other culprit  of the electrical short circuiting was the thumb screws that came included with the case to mount the motherboard to the standoffs. When you mount the motherboard with the thumbscrews it causes random losses of power which will cause system restarts every few minutes without any major blue screen errors leaving you scratching your head. The fix for this was to replace the stock screws with standard computer mounting screws.

One of the really neat things with this case is that it uses a two zone design. This design separates a large number of your drives from the rest of the system which helps to keep the overall system cool.

In practice, this worked really well. The split zone design also made cable management a bit easier by allowing me to use the full length of my cables. I tested the strength of the cooling in zone one by placing 3 drives in the drive cage, 2 Western Digital VelociRaptors and a  2TB Segate barracuda XT. Once I had all the drives in and everything set up with it I was very surprised at how well the single fan kept them cool.

  1. I never saw any issues with shorts, do not see how the standoffs on the mobo or using the thumb screws instead of regular screws would cause a short, nor could i see how an electrical short could result from the use of the power supply mounting bracket, that is very very strange.

    -I would not call this case perfect either, the bottom hard drive bracket is too close to the power supply, causing cable cramp, and it is also not perforated, whereas the hard drive cage at the top in the upper zone is perforated, which means that your bottom mounted hard drives are not getting properly cooled.
    -The area at the top is too hard to work with, getting 8 pin power installed is difficult because there is little clearance with the motherboard and the wall between the upper zone and main zone.
    -The hole in the motherboard tray for the behind the cpu access is nice too, but….there is no cover, so you just have a huge hole in the motherboard tray.
    -The cable routing holes are not the best aligned in the world and could be wider to give more room, and there are no rubber grommets to seal them like in the Corsair cases.
    -I know a lot of people use their cases usb/ports clusters, but I usually do not and either way there are a lot of cables to have to store or route, making the area in the upper zone very cluttered with a lot of cable bulk, proving difficult to install multiple 5.25″ bay devices.
    -The cable routing in the back, while nice, could use a bit more room between it and the case cover, I would say it is not quite deep enough.
    -The supplied tool-less expansion card mounting system is OK, but i found it too hard to use when you wanted to remove/add cards frequently, you have to get the card situated just right to fit under the holder, but fortunately, this is removable.
    -The case is too expensive.
    On the plus side, there is great direct cooling right on system components from the three front 120mm fans. I replaced these with more powerful fans as the supplied 120mm fans while silent i found didn’t push enough air. The case is not too loud. I would also liked to have see individual fan controllers as well, not just the one master controller. Sometimes i wonder if these case manufacturers ever work with their own cases to build systems.

    • I never had any problems with electrical shorts either, it must be your houseplug that’s not properly grounded. otherwise your components may be defectice.

      Nice review, besides talking about issues that has nothing to do with the chassis and by that giving it bad reputation.

      Buy this chassis, expensive – so what, if you have the money to spend on it, it’s worth it

      • I thoroughly tested this case before post the problem with the electrical short. while this short may not be present in all the cases in production it was present in the model I reviewed.
        This case was tested using 2 different motherboards, 2 different power supplies and on different circuits. Both motherboards and power supplies that I used to verify that there was indeed an issue are stable boards that are actively in use.

        • I had no problems at all with electical shorts. The included fans were better than I had expected, as well as cooling. The X900 cools as good as my Silverstone FT02, but with less noice. Maybe I got a slight revision of the case, as my bottom harddrive cage has holes for a SSD-drive.
          Compared to the X1000, the X900 has reinforced sides, as well as better quality fans. This, along with the nice side-window makes it a good buy. There is always a price for design and quality.
